Overview

The LA7530N is an IC containing the VIF section and SIF
section on a single chip in the DIP20 package. The use of
the small-sized package serves to make VCR tuner units
smaller.
As compared with the LA7530, the LA7530N is provided
with 2 pins for IF AGC, permitting higher AGC speed. The
LA7530N can substitute for the LA7530, but the LA7530
cannot substitute for the LA7530N. For 9V supply , use the

LA7533.

Functions

• VIF section :VIF AMP, VIDEO DET, PEAK IF AGC,

• SIF section : SIF LIMITER AMP, FM DET , SND MUTE.

B/W NOISE CANCELLER, RF A GC, AFT,
VIDEO MUTE.

Usage Note : 1. Protective circuits must be inserted when using this IC with lines directly connecting the IC pins to external circuits.

(For example, this applies to pins 12 and 15.)

2. A 1000pF capacitor must be connected between either pin 5 and ground or between pin 5 and pin 8 to prevent VIF amplifier
oscillation.
